<p>A magnetic valve with permanent magnet closing force for currentless closing is actuated by an electromagnet which co-operates with a permanent magnet armature. The electromagnet consists of a U-shaped magnetizable yoke (6) which carries a coil (7). The pivotally mounted armature (3) is made of weakly magnetic material. A permanent magnet (4) is located between the armature (3) and the coil-carrying end of the yoke (6), the appropriate poles of said magnet being directed towards said parts. The magnetic valve controls the outflow opening of a container for liquids (1), e.g. a domestic machine, by means of an elastic, mushroom-shaped valve cone (2).</p> |
